MULTIPLE-TRIP CONTAINER Filed Dec. 9, 1944 Patented June 20, 1950 e. Q 7 V I .MIIL'EIBLEFLZEESLINZ'MINER This invention relates to multiple-trip containers of the: type usedfont-shipping. explosives where the empty box and lid are returned to the manufacturer for credit during 'ti'mes such asat present when frequently new materialis practrcally unobtaiiiablL:v Ittisthe; primeiobject of the invention; is provide a container of this. type where longer. life is assured by; means which, at thessametime, minimize thezliazard incidienttto th driving. of nails ihto the;.wobden boxes'usuall ,us'ed and also the use oil'claws wedges and other opening devices whichmayproduce dan- EI9Ll$ friction when the container: hasmeached ts-seamen.

A; further; object ofthe ihventio mis to,- provide a container which, altho employing but a single closing band, assuresagainst anyetampering with the contents of the box by'making it impossible: tDiI'GIIlQVBIrthB contentsiwithoutgiving visiblesevidence of that action. A stillzfurthen objectg'ofi'the invention iSrtD provideva"itwmpiececontainergheld assembled by loosely fitting dowels or other connections, which in turn are prevented from moving from retaining position. v

At the present time explosives are shipped in wooden boxes with a closing lid secured in lace by nails having heads engaging the top of the lid. Aside from the danger of driving a nail into the box chamber or space and therefore possibly into the explosive, there is always the hazard due to the impact of metal against metal in the driving of the nails into place, and this is true whether the nails are driven by hand or by machine. Furthermore, it frequently happens that the nailed lids are carelessly pried open with a consequent loss of the lid or damageto the box, resulting in. inability to reuse the container.

By means of the container hereinafter described impact and dangerous friction are eliminated, the life of thebox and the lid is greatly increased, and evidence is given if the contents of the box have been tampered with.

In the drawings Figure 1 is a perspective view of the preferred form of my container.

Figure 2 is an exploded view, largely in section. Figure 3 is an elevation of the box with the tape or band removed and the nails or other fasteners' withdrawn.

Figure 4 shows a slight modification.

Figures 5, 6, and 7 show different methods for securing together the two parts of the container.

In the preferred form of the invention as illustrated in Figures 1 to 3 the receptable member of the container is a box formed of a bottom Allentown, Pin, a cor I, L Anpllcatinm-Decembenii, 1944, Serial No. 56'7",3'74

" momma (Cl. aim-56x H 2r it; sides ll and" ends l2" of' a well-known type" and havingan open top; Where the cost isinoii prohibitive the bottom; sides. and ends are integrali, as for example: when the box; is formed by?" molding; as in-usingplastic ext-concrete:

Thefcoveri's preferably in two parts, the" top portion I"? being of plywood and of the same width" and length as the box bottom; and the lower portion being of ordinary box'board's' W permanently secured to the plywoodtbp' andbeing of such size as to fit'inside of the receptacle member. As shown in Figure 4', the cover member may be-irr one piece [8; but is otherwise-identical: with thecover |-5'-l I.

The" receptacle member is rabbet'ed at the top to forrrr a continuous k-erf "29 A plurality of'holes 21, at desired intervals; are provided to receive nails; dowels, or'otherheaded' or unheaded fastenihgmembers: These holes arecountersunk as" at ZZto: receive the head of the connectionrif the latter beheaded, and, it" ismy preference to en large the countersink as at 2 3 in Figure 3* to make it more-convenient to withdraw a" nail= or dowel by hand. A saw kerf 25 communicates with the kerf 2|].

In the preferred form the connections are nails 2'! of the shingle type fitting loosely in preformed holes 28 in the lid or cover in registry with the holes 2| thru the tops of the sides and ends. The word loosely is meant to imply that the friction is not too great as to prevent the ready removal of the retaining means, whether a nail or other fastener, without any danger to the contents of the container, if it be loaded with explosives. It is intended generally that the nails shall be inserted and removed by hand, and they may in fact be quite loose or may fit with enough friction to keep them from sliding in the registered holes.

When all of the connections or retaining means are in place they may be prevented from moving out of the holes by a means such as an adhesive tape 30, as in Figure 5. I prefer, however, to use acommercial band of the Signode or equivalent type. This is a strap 31 about a half inch wide and with apex turned edges. It is slightly narrower than the rabbet and may be drawn as taut as desired and then secured as by the seal 33. When so applied, the dowels or nails cannot be removed without first removing the strap fastener. This is readily accomplished by inserting shears in the saw kerf 25 to sever the band which then comes freely out of the groove between the rabbet and the top portion of the cover.

In Figure 5 the cover is a solid sheet 34 to which are secured brackets 35 pierced to receive the pins 36 and fitting within recesses 31 in the receptacle member. The band is here shown as a summed tape 30 Figure 6 is similar except the brackets 40 are secured to the receptacle member and are received in recesses 4| in the lid, and the dowels 42 are inserted thru the continuous kerf 44 located entirely in the cover member rather than in the lower portion of the box.

The container of Figure 7 is in two somewhat similar portions. One of these portions carries a bracket 59 which may be a continuous piece, suitably recessed to receive the fasteners, and receivable in a continuous groove 52 in the other member of the container. In this modification there is no kerf or rabbet corresponding to that numbered 20, but, instead the tape which is somewhat wider than usual, is applied directly to the outside of the box.

In any of the forms it is diflicult to tamper with the contents by removing the box bottom II! when of the ordinary type as the type of liner normally employed inside of an explosive package has only a top opening. As an added precaution, a single strip of lining material 54 may be used, as in Figure 4, extending from one side to the other in one piece and being perforated. by the nails. This would indicate any tampering from the bottom and used with the seal would insure genuine contents.

What I claim is:

1. In a multiple-trip container for explosives, a rectangular receptacle having a bottom, two sides, and two ends, with a rabbeted portion forming a recess extending entirely around the outer periphery of the top thereof and having holes extending through the rabbeted portion on opposite sides of the receptacle, a cover for the receptacle comprising a top portion to rest upon the receptacle and extending beyond the rabbeted portion flush with the major part of the receptacle to form with the rabbeted portions a groove, and a bottom portion fitting the four inner surfaces of the receptacle with its edges parallel thereto and extending into the receptacle a distance equal to the vertical dimension of the rabbeted portion and having in the bottom portion of the cover holes registering with the holes in the receptacle, retaining means fitting loosely in the registering holes in the receptacle and the cover, and strap means entirely within said groove or preventing withdrawal of the retaining means.

2. The device or claim l in which the rabbeted portion is countersunk adjacent to each hole for a a convenient access to the retaining means for the manual removal of same.

. 3. The device of ,claim 1 in which the entire box is of wood, the strap means is a metal band, and-the receptaclehas a saw cut communicating with therabbeted portion at right angles for facilitating the" cutting of the metal band by a pair of shears So that the retaining means may then be removed by hand.
